@Orion: It turns out that Arjen is correct. To confirm that try the following experiment: irwin@raven> tclsh % package require Tk 8.5.11 % exit A blank GUI shows up on the screen as the result of the "package require Tk" command even for a tclsh context (which normally is not used for anything to do with GUI's). Therefore, I am sure the above combination (which is also in our CMake sanity checking for Tcl/Tk versions) like the equivalent wish combination won't work for a Linux environment that does not have a working X display. Thus, the conclusion seems to be that your idea of specifying exact version numbers to skip all this consistency checking is your only PLplot configuration alternative when there is no working display. On the other hand, I think that inconvenience is acceptable since no working display is a pretty specialized case. Alan __________________________ Alan W.
